I'm still under construction,But,OK, I can chime in. 78 FJ40, bought with fiberglass tub ,78,000 miles. I find 76 body, ??? miles, By By FG tub. Now frame off. 350 Chevy V8 crate motor,2000 miles, VDO gauges , 0 miles, roll cage ,0 miles , Corbeau seats , my butt has sat in one once sinced purchsed,5minutes of butt miles, new SST's , .10 miles (I did roll it around the shop a couple times). Numerous aftermarket parts ( yet to be bolted on). You get my point. Your rig is what it is. If you are going MECUM ,do not roll the OD. If you are like me, Document, and save your reciepts. I'll step down from my soapbox now.
